Over 400,000 tickets have been sold for Brooks' gigs at GAA headquarters, with 100,000 country music fans set to jet into Ireland.

Rising country star Nathan Carter has also been booked in for two nights.

Furious campaigners have called on gardai to prosecute the GAA and Aiken Promotions for allegedly promoting the Garth Brooks Croke Park concerts illegally.

Homeowners who live in the area handed letters of complaint over to the Garda Commissioner Noirin O’Sullivan at midday yesterday, asking for criminal proceedings to be launched against the top companies.

The chairman of the Croke Park Streets Committee, a 600-strong residents group, said the country superstar’s gigs were promoted before the concert licence was given the green light.
